Thank you Mr. Che Kuan Yau...appreciate your usual prompt response.

@waross...i looked and found a complete list of codes for the representation of names of countries and their subdivisions https://www.ip2location.com/free/country-information for everyone's info thank you

@waross...yeah i saw it...thanks

pardon me @che12345... replying to your "1. No. Your system is 380V. Say + - 10% i.e. Hi 380V x 1.1 = 418V, or Lo 380V x 0.9 = 342V. How do you get 420V (+10%)?" i got it from the options below: 3ph × 200 V, 50/60 Hz 3ph × 220 V, 50/60 Hz 3ph × 230 V, 50/60 Hz 3ph × 400 V, 50/60 Hz 3ph × 420 V...

@che12345...+/-10% acceptable value for a 380V power supply should be 420V (+10%) as the closest number than 400V, would you agree? although 400V is most common from where I am. thank you very much still for the refresher:) @waross..."..the code tells where your internet provider connects to...

thank you everyone for sharing. apologies waross, these voltage/frequency/ph ratings I mentioned, i.e., 3ph × 200 V, 50/60 Hz 3ph × 220 V, 50/60 Hz 3ph × 230 V, 50/60 Hz 3ph × 400 V, 50/60 Hz 3ph × 420 V, 50/60 Hz 3ph × 460 V, 50/60 Hz ...were not sources, these are the various ratings of the...

Hi, an electrical stub out says 380v/60hz/3ph. Which of the machine voltage ratings below are acceptable/recommended? 3 × 200 V, 50/60 Hz 3 × 220 V, 50/60 Hz 3 × 230 V, 50/60 Hz 3 × 400 V, 50/60 Hz 3 × 420 V, 50/60 Hz 3 × 460 V, 50/60 Hz These are the only voltage available for the said machine...

@MedicineEng - Thank you for the advise. We already did this and due to weak suction of exhaust hood, we can barely see make up air doubling back through exhaust hood. But, it appears make up air 5 and 6 does. @chicopee - it is belt-driven. This is my initial findings actually in lieu of...

Hi, AdrienneGC. Thanks for your feedback. These are great references. Appreciate your help on these.

Thanks everyone and apologies for the late responding as I was away. Just to let you know, we are near the equator (southeast asia - the Philippines). We will work on the exhaust system since its easier to modify on the fresh air based from the list of equipment computed CFM required to move...

@LittleInch - further to my aboe message, attached herewith is the complete data I gathered.https://files.engineering.com/getfile.aspx?folder=2f9637e9-85bd-4e69-99ce-2e2dc7e21299&file=KITCHEN_VENTILATION_DATA.xlsx

Dear All; Thank you very much for taking the time to respond to my above message. @LittleInch - Yes, ACR is the Air Change Rate. ACR 60 seems right from what I've read. Total air inlet flow rate of 32,016 is a combined ambient air @77°F (26,562) and air-conditioned air @68°F (5,454) and their...

Hello, everyone. I have a friend who is an executive chef seeking my help about his kitchen which is discomforting to him and with his staff. The last HVAC contractor who made the rehab of his kitchen supplied them with a motor capacity that is half the capacity from the originally installed...

Thank you all for the very helpful tips. I have managed to persuade the bldg administrator which is also the owner of the kitchen to install a transformer dedicated for his kitchen only (Thanks, Waross and ScottyUK). Yes, Paulusgnome, based from the Instructions Manual, though unit is spec'd...

A local distributor insists on having a 208V 50-60HZ 3PH induction range unit plugged in on a 240V 60HZ 3PH power supply stub outs. I told him the manufacturer puts the specs 208V on the unit's data plate for a reason and when I asked him how does it affect the overall performance of the unit...
